MERCER ISLAND - Drivers trying to go from Island Crest Way to the Mount Baker Tunnel can expect delays this weekend as crews close all but one lane along the stretch of road overnight Saturday.

WSDOT advises the on-ramps from 76th Avenue Southeast and West Mercer Way to westbound I-90 will also be closed from 9:00p.m. Saturday to 3:00a.m. Sunday.

A detour to the 77th Avenue southbound on-ramp to the I-90 express lanes will be available.

During the closure, crews will service the lights inside the Mercer Island Lid. All but one of the lanes from Island Crest Way to the Mount Baker Tunnel will remain closed until 10:00a.m., Sunday, Feb. 24.
